Installing Redhat Enterprise 4 x86 on DL360 G5

Hi,

I'm trying to install Redhat Enterprise 4 on a DL360 G5 using 2 mirrored disks on the onboard Smart Array P400i controller. Installer can't detect controller and the server doesn't have a floppy drive to use the driver from HP.com.

Can anybody advise a way to get around this? I've tried selecting the LSI Fusion MPT drivers from the list but still get the message that no valid devices were found to create new filesystems.
